The purpose of this study was to examine the relationship between self-reported exercise behavior and physiological indicators of exercise behavior (body composition and oxygen consumption measures) in older women. Three self-report exercise behavior instruments were administered in counterbalanced order. Body mass index and sums of skinfold thicknesses were used as measures of body composition. Oxygen consumption was measured using a metabolic cart during a treadmill test while women walked at approximately 70% of their heart rate reserve. Fifty-nine women participated (68.7 ± 6.0 years). Results showed that self-reported exercise behavior was moderately related to body composition measures. However, predicted maximal oxygen consumption was only weakly related to self-reported exercise behavior.
